Rotor 3D+ INpower crankset

ROTOR introduces multi-discipline power meter
IN the future, all high-end cranks will feature a power meter INside

Due to its position inside the frame, INpower is available in any 30mm ROTOR crank for MTB, road, and triathlon/TT, which affords mountain bikers, 'cross racers, and triathletes the same pursuit of physiological gains historically enjoyed by road cyclists. With a nod toward ROTOR's flagship Q-Rings, INpower features TORQUE 360 and Optimum Chainring Angle (OCA) pedal analysis, which help cyclists precisely and accurately assess force variations in their pedal stroke. TORQUE 360 and OCA values enable cyclists to orient their Q-Rings around their distinct pedaling characteristics in order to take advantage of their most productive zone.

"We wanted to create a power meter that overcame current trends in power meter technology and could be transferred to other disciplines," said Pablo Carrasco, head of research and development at ROTOR and INpower's inventor. "At the same time we wanted to leverage the benefits of Q-Rings and build a sophisticated power meter that's fairly simple to use compared with other power meters out there."

INnovative features and INtelligent metrics
INpower uses a standard AA battery and is equipped with the UBB30 axle system, a 30 mm diameter axle that is compatible with almost all standard frames in the market. Because INpower measures data in the left leg, cyclists who already own a current set of ROTOR cranks have the option to purchase only the left crank arm and install it themselves with the help of a downloadable multi-lingual user's manual. Because it's centered in the crank axle, INpower achieves cleaner data transfer and greater accuracy via ANT+™ protocol without succumbing to interruptions and temperature fluctuations. Sophisticated metrics like Torque Effectiveness and Pedal Smoothness determine total torque versus positive torque and average power versus maximum power respectively.
